The dental machine lfl includesa suction line I2 which has P mounted on itsouterend a suction hood lo, the

suction hoodlpq beingadapted to be mounted in a pa ent mo h o .s em ne abr s v a: terial therefrom during theprocess of drilling teeth with, the fluid blast drill. Inorder that the suction hood I4.may be suitably positioned with respect, to a patients mouth during the drilling operation, the dental machine I 0 is provided with a suction hood holder, which is referred to in general by referencetnumeraljfi. v H v l Referring now to Figures 2 and 3 inparticular, t.;will be seenthat the'suction hood holder 16,

whichis the subject of this invention, includes a:

telescoping arm, which. is referredto .in'general by thereference numeral [8, which, is connected to amounting bracket, which is referred to in general by the reference numeral 29, by a swivel connection, which is referred to in general by h re reme numera 22-, T eles n ar QB. a ec to .theire' he o v s c oniood si h nin clam in- Irvin bs ts ha the telescoping arm [8 includes an elongated tubular member 26 in which is telescopically received the inner end of an elongated rod 28. The elongated rod 28 may be extended with respect to the tubular member 26 and is retained in an adjusted position by a locking screw 30 which is threadedly engaged in an internally threaded bore of a boss 32 carried by the upper side of the tubular member 26 at the outer end thereof.

The mounting bracket 28 includes a firstarm 34 which is provided with a plurality of spaced apertures 36, the apertures 36 receiving fasteners 38 which secure the arm 34 to the dental machine Ill. The mounting bracket 20 also includes an arm 48 which is at right angles to the arm 34 to which the swivel connection 22 is secured.

The swivel connection 22 includes a vertically extending sleeve 42 which is secured at its mid.- point to the free end of the flange 48. Secured to the upper and lower ends of the sleeve 42 are inwardly turned telescoped ends 44 and 46 of spaced parallel vertically extending plates 48 and 58, respectively. The inwardly turned ends 44 and 46 of the plates 48 and 58, respectively, are pivotally secured to the sleeve 42 by a vertically extending fastener 52 which extends through both the sleeve and the ends. The fastener 52 is provided with a knurled head 54 at the upper end thereof and is threadedly engaged with a nut 56 carried by the lowermost inwardly turned end 46 of the plate 58. When the fastener 52 is loosely disposed within the sleeve 42, the plates 48 and 58 are free to pivot about a vertical axis through the center of the fastener 52. When it is desired to lock the plates 48 and 50 with respect to the sleeve 42 and associated flange 48, the fastener 52 is threaded further into thenut so as to produce a clamping action.

Referring now to Figure 4 in particulanit will be seen that the spaced parallel plates 48 and 58 are provided adjacent their'other ends with a transversely extending fastener 58- which passes through a bore 68 in the plate 50 and is threadedly engaged in an internally threaded bore 62 in the plate 48, the bores 68 and 52 being horizontally aligned.- In order that rotation of the fastener 58 may be facilitated; it is provided with a knurled head 64. The fastener'58 also passes through aligned bores 68 in the inner end of the tubular member 26, which is disposedbetween the spaced parallel plates 48 and 58.

In order that the tubular member 26 may be properly supported between the spaced parallel plates 48 and 58 and also clamped in an adjusted position, there is also mounted on the fastener 58 a pair of cup-shaped members 68 which abut each other and their respective plates 48 and 58, the cup-shaped members 68 retaining the plates 48 and 58 in spaced parallel relation. The cupshaped members 68 are provided with aligned recesses inwhich is received the inner end of the tubular member26, the inner end of the tubular member being rigidly supported by the cupshaped members 88 for rotation about the horizontal axis passing through the center of the fastener 58.. It will be understood that, the cupshaped members 68 rotate when the tubular member 26 of the telescoping arm [6 is ivoted and that the telescoping arm l6 may be secured in an adjusted relation by tightening down upon the fastener 58 to clamp the cup-shaped members 68 between the spaced parallel plates 48 and 58. l

Referring now to Figures 2 and 3 in particular,

it will be seen that the suction hood supporting clamp 24 is in the form of a generally U-shaped;

spring clamp which has secured to the rear side thereof a ball 12 which is mounted in a socket 14 at the other end of the elongated rod 28 to form a ball and socket connection. The ball 12 is of such a size whereby it may be removed from the socket l4 and, therefore, is retained within the socket 14 by a locking screw 18 threadedly engaged in an internally threaded bore of a boss 18 mounted on the upper side of the socket housing 80. It will be understood that the locking screw 16 also clamps the ball 52 in an adjusted position within the socket 14, whereby the angle of the suction hood supporting clamp 24 may be varied with-respect to the telescoping arm l6.

"Referring now to Figure 6 in particular, it is seen that there is' illustrated a modified form of suction hoodisupport clamp, which is referred to in general by the reference numeral 82. The suction hood supporting clamp 82 is generally cylindrical in outline and has a pair of spaced par-- allel flanges 84 to form a split ring clamp. Carfied by the flanges 84 is a fastener 86 for urgingthe flanges 84 together to provide a clamping;

action. The suction hood supporting clamp 82:

set forth relative to the ball 12.

Referring now to Figure 7 in particular, it will be seen that there is illustrated still another modified form of suction hood supporting clamp, which is referred to in general by the reference; numeral 98. The suction hood supporting clamp J, 98 includes a pair of clamp halves 82 and 88 which are semi-circularand have outwardly extending flanges 8G and 98, respectively, at the ends thereof. The clamp halves 92 and 84 are secured together by fasteners I88 which pass through apertures I82 in the flanges 98 and are threadedly engaged in threaded apertures 104 in the flanges 96. The clamphalf 62 is provided with a ball N36,, which is similar to the balls 'i 2 and 88, and is secured within the socket 14 of the housing 88 by,-

the locking screws- 16.

While the mounting bracket mountingbracket 28 may be equally as well se-- cured to a wall or other supporting structure ad jacent a dental chair, however, it will be under-- stood that regardless as to what structure the mounting bracket 28 is secured, the relationship of'the suction'hood holder IS with respect to a patient seated ina detail chair must be such that the suction hood l-4may be held in the proper position relative to the patients mouth. It will be understood that the various adjustments of the suction hood holder 1 6 permit the mobility of the suction hood and adapt the same to be positioned as desired with respect'to the patient in the dental chair, and at the same time provide a stable support for the suction hood i4 when placed in a position so as toeliminate the requirement for an assistant to hold the suction hood and allow the suction hood to be positioned for maximum recovery of the basic materials utilized in the drilling process.

The operation of this device will .be understood from the foregoing; description of the details 3 thereof, takenin connection with' the'labove'.re-"
